Separating hydrogen and oxygen evolution in alkaline water electrolysis using nickel hydroxide

Alkaline water electrolyzers are promising devices for hydrogen generation, although hydrogen/oxygen mixing can be problematic. Here, the authors use nickel hydroxide as a redox mediator to decouple the hydrogen and oxygen production, overcoming the gas-mixing issue.
